Lockheed Martin (NYSE: LMT) and Kongsberg Defence & Aerospace
(Kongsberg) of Norway have entered into a Joint Marketing Agreement
to market an air-launched version of the Naval Strike Missile.
The 1,000 pound stealthy missile, to be called the Joint Strike
Missile (JSM), is designed to be carried internally and launched
externally from the F-35 Lightning II aircraft, striking surface
or land targets at ranges of up to 130 nautical miles with high
precision.

The JSM uses a titanium warhead and programmable fuze to augment
its effectiveness against hardened targets. The missile's guidance
employs Global Positioning System/Inertial Navigation System
(GPS/INS) guidance with an imaging infrared seeker and an automatic
target recognizer (ATR). JSM is equipped with an in-flight data
link enabling the operator to update the missile's target data
in flight.
